Stratara.Testing

Derived. The behaviour described here is specified under openspec/specs/. Those specifications are the source; this page explains and illustrates them.

Test doubles and assertion helpers for applications built on the Stratara framework. Unit-test your event-sourced aggregates, encryption, messaging, and session-aware code without spinning up Postgres or RabbitMQ testcontainers.

Contents

  • AggregateTestHarness<T> / Aggregate.Rehydrate<T>(...) — given/when/then rehydration of an aggregate from events, using the same Apply(...) dispatch as production. Throws on an unmapped event so a forgotten overload fails the test (opt out with IgnoringUnmappedEvents()).
  • InMemoryKeyStore — an IKeyStore that mints random 256-bit DEKs per scope and supports rotation / revocation / scope-erasure, without a master KEK or key file.
  • TestBlobEncryptor.CreateAesGcm() — the real AES-GCM ISecureBlobEncryptor over an InMemoryKeyStore, so blob round-trips exercise production encryption.
  • InMemoryMessageBus — an IMessageBus with synchronous in-process dispatch and a Published list for assertions.
  • TestSessionContext / TestSessionContextProvider — preset Actor/Subject SessionContext values and an ISessionContextProvider double.
  • InMemoryTenantMembershipStore — an ITenantMembershipStore mirroring the EF store's contract semantics, including the membership-guarded active-tenant selection and the erasure sweeps.
  • InMemorySettingStore — an ISettingStore with exact-scope reads/writes, so the scoped-settings fallback chain can be exercised without a database.
  • InMemoryApiKeyStore — an IApiKeyStore mirroring the EF store's contract semantics: issuance, idempotent import of a caller-supplied key, fail-closed validation, revocation, erasure sweeps, and machine keys materialized into a membership store you can share and inspect.
  • TestTenants.Of("acme") — stable, deterministic tenant/user ids derived from readable slugs.
  • TestEvent.Create(payload, ...) — wrap an event payload in IEvent<T> with realistic metadata.
  • ProjectionTester.HandleAsync(projection, event) — invoke a projection's (private) HandleAsync handler directly, so you can unit-test it against mocked repositories.

Example

var account = AggregateTestHarness<Account>
    .Given(new AccountOpened(id, "Ada", 100m))
    .And(new AmountWithdrawn(id, 30m))
    .Build();

Assert.Equal(70m, account.Balance);

Dependencies

  • Stratara.Abstractions, Stratara.Contracts, Stratara.Shared, Stratara.Security
  • Microsoft.Extensions.DependencyInjection

Reference it from your test projects only (<PackageReference Include="Stratara.Testing" />). It is not meant for production code paths — the InMemoryKeyStore and DummyKeyStore provide no durability or KEK custody.

Stratara.Testing.EntityFrameworkCore

Spin up the real Stratara event-sourcing write stack (EventSource, aggregation, snapshots, the EF Core write store) against a shared in-memory SQLite database in one call — production code paths, no Postgres, no Docker. Builds on Stratara.Testing's in-memory doubles.

A fix for hosts on the Orleans execution model. A store reader that catches up a large backlog and a singleton
work that runs long now answer their keep-alive, so neither leaves reminder errors in the silo's log. A silo that
joins while a singleton work runs long on another silo no longer fails its start. No API change, no schema change
and no migration.

### Fixed

- **A busy store reader or singleton work answers its keep-alive.** On the Orleans execution model, a projection or
 saga reader that caught up a backlog for longer than the runtime's response timeout made its keep-alive tick wait
 behind the catch-up, and Orleans logged `Could not deliver reminder tick` at Error, once per partition and
 keep-alive period. A singleton work whose run outlasted the timeout did the same. Nothing was lost, but a large
 catch-up left dozens of errors on the silo. The keep-alive and the poll now start a catch-up where none is
 running and do not wait for it. A partition is still read by one catch-up at a time, and a commit during a
 catch-up is still applied by it. A singleton work's keep-alive interleaves with its run, and runs still never
 overlap.
- **A silo starts while a singleton work runs long.** A silo that started while a singleton work it registers ran
 longer than the response timeout on another silo waited for that run in its own start. The start then failed
 with a `TimeoutException`. The call a starting silo makes to each singleton work and store reader now
 interleaves, so the start goes on.
- *Operate the Orleans execution model* says that a durable timer whose handler outlasts the response timeout
 still makes Orleans log `Could not deliver reminder tick` for that tick, and that the line says nothing about
 the timer. It also says that, outside a deploy, the line now points to an unreachable store reader or singleton
 work rather than a busy one.
